Assigned text to button wont appear on my php contact form

I have created some buttons on a contact page that uses GET to feed a contact.php script. The problem is I cant seem to get the message variable to read into the email that it generates.

The website is www.tanyapowell.com.au, its the adelaide site.

the action script I use for the button to assign the text is


on(release){
message= "12 week teen modelling and grooming"
gotoAndStop(1);
}


this should assign the variable message that token and then have it moved to the contact email using GET

the GET script is

$your_message = $_GET['message'];

and the content reader is

$content .= "Course of interest <b>" . $your_message . "</b><br>";
